Short version: An insane, bloody, gratuitous, funny rollercoaster of a movie that doesn't pretend to be anything beyond that

Going in, the one thing I didn't expect this movie to be was funny. I had more laugh out loud moments during Crank than I did while watching the supposed comedy Clerks II. Before you decide to go see this, be aware that it earns its R-rating on every level: content, situations, language, violence, gore, sex and nudity. (Fine, now everyone will rush out to go see it.)
